Abstract: 959,186. Variable-speed friction gear. NATIONAL RESEARCH DEVELOPMENT CORPORATION. Aug. 18, 1960 [Aug. 19, 1959], No. 28397/59. Heading F2D. In a change-speed friction gear of the torus disc and roller type the rollers 51 are mounted in carriers 53 tilted by rockers 21 which are pivoted on the gear casing and have arms 22 extending into slots 26 in a common cam 23. Each slot 26 contains a guide member 27 having a bore 28 slidably receiving the end 29 of a rocker arm 22, friction between the end of the arm and the bore being provided by a circlip (not shown) or (Fig. 3) by a wavy spring 37 provided in a groove 35 in the arm 22. The shank 36 of the rocker arm above the groove 35 is relieved so that it is elliptical in crosssection (Fig. 6) to permit slight tilting of the rocker arm in the direction of the minor axis of the ellipse, that is axially of the gear. A wavy ' spring 32 in a groove in the slot 26 or the guide 27 generates friction when the guide moves relatively to the slot.

Title: Improvements relating to gill boxes for use with drawing, roving and like frames
IPC: D01H5/04
Filed: 1921-10-26
Abstract: 188,194. Mackie & Sons, Ltd., J., and Wilson, J. Oct. 26, 1921. Gill boxes and frames.-The faller bars are moved forward continuously along an upper guide track and returned to the feed end by revolving cams or carriers, independent of the means employed for the forward movement. During the return movement the fallers are turned to leave and enter the sliver at right angles and are also cleaned. The fallers 1, Fig. 1, are moved along an upper track 6 by a pair of screws 4 and returned by carriers 7 past cleaning brushes 25. Each faller has a cut-away portion to engage the screw 4 and a projecting end. The track 6 is shaped to engage the projecting end and support the faller 1 along its flat bottom surface. The cams 7 are provided with recesses 14 into each of which, as it comes into position, the projecting end of a faller is pushed. The faller is also engaged by a fixed guide race 21 so curved at one portion as to provide a shoulder 27 which will engage with the semicircular cutaway part in the faller. At this point the faller is turned over, the jar being softened by spring buffers 28. To ensure correct engagement with the screws 4 the fallers engage yielding guides 30. The projections on the carrier 7 are formed with shoulders 15 and receding surfaces 37 to prevent one faller dragging the next one down at the delivery end. The screws 4 may be replaced by a cam 34, Fig. 4, which engages the end faller and pushes the remainder in front of it. In such a case in order that the faller may be turned over in the fixed guide track, the faller is moved into a notch in the outer guide member and tripped over by the shoulder of this notch.

Abstract: 724,382. Plastering. BUTTER, O. Oct. 15, 1953 [Nov. 7, 1952], No. 28476/53. Class 20 (4). [Also in Group XXIX] A machine for plastering a wall or ceiling 3 consists of a housing 6 secured to a part 5 which is movable along guides 1, 2, the housing having a flared mouth 8 containing a highspeed grooved roller 9, a flexible rail 12 bearing on the top of the roller and a deflector 18 which ensures that plaster supplied by a pump (not shown) through the pipe 16 to the back of the roller is evenly distributed therealong, the arrangement being such that the plaster carried in the roller grooves past the rail 12 is thrown against the wall or ceiling, excess plaster being strickled off, as the machine moves along the guides 1, 2, by the trailing edge of the mouth 8, and returned, by the rotating roller, to the back of itself. A rail 13 opposite to the rail 12 may be provided, and both rails are sufficiently flexible to permit the passage of small stones. The roller 9 is driven by a motor on the part 5, through a chain, belt or shaft, the same motor being employed to effect the movement of the part 5 on the guides 1, 2, the motor shaft, for this purpose, being provided with a pinion which meshes with a rack on the guide 2. Limit stops 21, 22 switch off the motor when the part 5 reaches its end positions. The grooves in the roller 9 may be continuous or interrupted, and they may be inclined in opposite directions relatively to the roller axis, to form a criss-cross pattern. The speed of the roller 9 may be adjustable according to the kind of plastering being done.

Title: Squelch circuit for radio receivers
IPC: H03G3/26
Filed: 1951-12-07
Abstract: 699,592. Radio receiving circuits. BENDIX AVIATION CORPORATION. Dec. 7, 1951 [Dec. 29, 1950], No. 28770/51. Classes 40 (v) and 40 (vi). A muting system for a frequency-modulation receiver comprises means for amplifying and rectifying noise, the rectified product being applied to a muting device to mute the system, and is characterized by means for applying rectified signal to the noise rectifier so as to prevent muting and, in addition, means for deriving the envelope of the audio output of the system and applying it to reduce the gain of the noise amplifier. A noise amplifier 15 is coupled to the discriminator 11 by a network 14, 40 passing only the higher audio frequencies, and feeds noise to the cathode of a grid-controlled rectifier 17. In the static state the rectifier 17 passes current and a positive D.C. potential is applied from its cathode, via a low-pass filter 33, 43, to the grid of a D.C. amplifier comprising a pair of valves 34, 36. The valves 34, 36 are in series connection and the anode circuit of the valve 36 contains the winding 39 of a muting relay. The valve 17 being conductive, its rectification efficiency is low and also its cathode impedance, so that the gain of the amplifier 15 is also low and the circuit is insensitive to noise. When a signal carrier appears, a negative potential is produced by rectification at the grid of the limiter 12 and is applied to the grid and cathode of the valve 17 via resistances 18, 20 and 18, 19 respectively; circuit elements are so chosen that these paths have different timeconstants and the potential finally applied to the cathode of the valve 17 is a fraction of that applied to the grid. The appearance of a sufficient negative potential across the resistance 21 biases back the D.C. amplifier and causes the muting relay 39 to be released. The arrangement is such that, in the region in which the grid and cathode of the valve 17 are at about the same potential, the rectification efficiency of this valve is high and its loading on the amplifier 15 largely removed. The sensitivity to noise is then high, so that if noise accompanies the signal production of a sufficient negative potential across the resistance 21 to release the relay 39 is delayed, due to rectification of noise in the valve 17, until a higher signal level is reached. In addition, the audio output from the final stage 25 of the receiver is applied to a diode rectifier 28, which is provided with a delay bias by means of resistances 29, 42. Thus if the audio output is adequate, a negative potential appears across the smoothing network 30 and is applied via switch 44 to bias back either the amplifier 15 or the rectifier 17. In this way muting as the signal level falls is delayed until the audio output is unsatisfactorily small.
